Allergic rhinitis is a global disease whose main symptoms are nasal itching, continuous sneezing, nasal congestion and runny nose, which seriously affect the quality of life and social learning. In recent years, the incidence of this disease is gradually increasing. The nerves in the nasal mucosa have the function of regulating the secretion of nasal glands and vasodilation and contraction, and the nerves in the nasal mucosa of patients with allergic rhinitis function abnormally, i.e. parasympathetic nerve is hyperactive. Itchy nose, continuous sneezing, endless runny nose, etc. The aim of treatment is to relieve symptoms in a timely manner during the acute phase, and to find the allergen and avoid re-exposure after recovery. The effect of local medication is more effective in removing the disease. In the pathogenic stage of allergic rhinitis, the symptoms of runny nose and nasal congestion are mostly caused by the swelling and increased secretion of mucosal cells. 1. antihistamines, which can bind to histamine receptors in a short time, thus increasing the stability of various inflammatory cell membranes and reducing permeability, eventually reducing the edema and vasodilation of inflammatory nasal mucosa, inhibiting inflammatory reactions and reducing antibody synthesis, thus causing the release of histamine and other allergy-active substances 2, the use of glucocorticoids is also more widespread, which is a very potent inhibitor of inflammatory response, can inhibit the release of a variety of inflammatory factors, so that the local microenvironmental metabolism is improved, reduce exudation, and at the same time can inhibit the lymphocyte response, more effective treatment of disease. 3.Immunotherapy In drug therapy, more scholars believe that specific immunotherapy is worth recommending the use of immunotherapy. The course of treatment is divided into dose accumulation phase and dose maintenance phase, the total course of treatment ≥ 2 years, should be used standardized allergen vaccine, by qualified personnel to follow the principles of standardized treatment at the same time more need to provide psychological comfort and encouragement to patients, because this treatment often requires daily medication, the cycle is long, many patients can not adhere to. 4, surgery, in the treatment of allergic rhinitis, if the corresponding surgical indications, you should communicate with the patient as much as possible to treat the disease at its root, but in the choice of surgical treatment should still follow the general principles, that is, anatomical abnormalities (such as nasal septal deviation, nasal polyps), after strict medication and can not relieve the symptoms of patients. Common indications for surgery include no improvement of nasal congestion symptoms with medication or immunotherapy, significant signs that affect quality of life, and finding it more difficult than during the same period even in remission, and pterygoductal neurotomy is effective in the treatment of allergic rhinitis. Pterygoductal neurotomy is an effective surgical method, and nasal endoscopic pterygoductal neurotomy for allergic rhinitis has the advantages of being minimally invasive, highly effective, and with few recent recurrences after surgery is an effective supplement to traditional surgery and medication. Therefore, nasal endoscopic pterygoid nerve dissection is worth adopting as a new treatment method for allergic rhinitis.
